Abstract: A noncontacting mechanically actuated keyboard type switch and interconnecting networks for switch arrays are described herein. The basic switch is a balanced or differential transformer element with a movable magnetic core, or shorted turn, actuator (4) which is inserted through one-half of the transformer element, one primary-secondary winding pair (2, 6), causing the transformer to change from a balance or "off" state to an unbalanced or "on" state. The single turn coils that make up the differential transformer element lie in a plane, and in one embodiment of this invention the primary coils and their interconnecting network are printed on one side of a double sided printed circuit board, and the secondary coils and their interconnecting network are printed in proper alignment on the opposite side. A hole is provided through the printed circuit board for each transformer element for insertion of a magnetic actuator. Also described is a two dimensional X-Y switch matrix and a three dimensional X-Y-Z switch matrix, for facilitating electronic scanning of the keyboard for implementing encoding, multikey rollover, etc., techniques.

Abstract: Des ensembles moteurs auparavant utilises pour des navires auxiliaires, tels que par exemple des remorqueurs, manquent de souplesse de fonctionnement, de controle et de localisation, et ne sont pas aussi efficaces qu'ils pourraient l'etre. Afin de resoudre ce probleme, des unites de controle de puissance sont utilisees pour controler les moteurs a courant continu qui sont utilises pour entrainer les helices. Des moteurs diesel (10) sont utilises pour entrainer des generateurs a courant alternatif. Le debit de ces generateurs est fourni aux moteurs a courant continu (20) qui entrainent les helices (24) du navire, les moteurs a courant continu (20) sont controles par des rectificateurs de controle au silicium (17) et des controles de courant sensible (18). Un autre avantage de l'utilisation d'un tel ensemble moteur reside dans le fait que les moteurs diesel (10) peuvent etre places dans la partie avant du navire et les moteurs a courant continu (20) peuvent etre places dans la partie arriere du navire pour des besoins d'assiette ainsi que pour recouvrir l'axe de l'helice. Les benefices de cet ensemble moteur lorsqu'il est utilise dans des navires auxiliaires se traduisent par une economie de carburant et d'espace.

Abstract: Presse etoupe (10) et methode, utilises, par exemple, avec un trepan de forage rotatif dans l'industrie du petrole, comprenant une bague metallique annulaire (12), un corps elastomere annulaire (14) et une garniture en polytetrafluorethylene (16). Le joint (10) possede une levre lubrifiante s'etendant axialement vers l'interieur (18) et une levre a boue s'etendant axialement vers l'exterieur (20). Lorsque la pression du lubrifiant depasse une valeur donnee pour laquelle le joint a ete concu (par exemple de l'ordre de 100 a 200 psi), la pression provoque l'inversion du sens de la levre lubrifiante (18) et permet la vidange du lubrifiant, celui-ci s'ecoulant axialement vers l'exterieur au-dela des deux levres jusqu'a ce que sa pression soit reduite, apres quoi la levre lubrifiante (18) reprend sa position d'origine. Pendant la purge, la levre de boue (20) joue le role d'un etranglement controlant la purge et empechant l'acces de la boue de forage.

Abstract: A structurally toughened heat resistant adhesive composition comprising a solution of butadiene-styrene block copolymers in polymerizable acrylate ester monomers. The adhesive composition also contains an adhesion promoter, a cross-linking agent, a free-radical generator and a free-radical accelerator. The adhesive compositions are generally used as two-part systems, and yield bonds with improved heat and solvent resistant properties. 
     The polymerizable acrylate ester monomers may be monofunctional or a combination of mono- and polyfunctional monomers. Among the useful classes of monomers are alkyl and cycloalkyl acrylates, alkyl and cycloalkyl methacrylates, alkoxy acrylates and methacrylates, alkylene diacrylates and dimethacrylates. A few of the preferred monomers are methyl methacrylate, lauryl methacrylate, isobornyl methacrylate, and tetrahydrofurfuryl methacrylate. 
     It is preferred that the butadiene-styrene rubbers be block copolymers with the structures of (A)n(B)m, (ABA)n or (A-B)n, wherein A represents a polystyrene chain and B represents a polybutadiene chain; n and m are integers greater than or equal to one (1) and define the number of repeating units. Additionally, these structures generally contain a functional group at one or both ends of the plymer chain. Suitable functional groups are vinyl, epoxy, carboxy, and mercapto groups.

Abstract: A medium consistency oxygen delignification process and apparatus, utilizing one or more substantially horizontal agitated tubular reaction zones (10). 
     The use of rotary screws or paddles (24) in the reaction zone or zones provides the agitation required to enable good mixing of oxygen with the medium consistency pulp and alkaline chemicals as well as the control of the pulp retention time in each reaction zone (10). 
     In one embodiment of the invention, pulp is transported from the cooking stage through line (54) to screens (56) where oversize slivers, shivers, knots and other impurities are removed. The accepted pulp passes through line (58) into pulp washer (50) while the rejected material is sent to refiner (52) for further fiberization before being recombined with the main pulp stream through line (60). This combined pulp stream is then washed and oxygen- delignified as described above to yield a bleachable grade pulp.
